Psychological Reports, 2010, 107, 2, 447-462. © Psychological Reports 2010 SELF-LEADERSHIP AND VOLITION: DISTINCT AND POTENTIALLY SUPPLEMENTAL CONSTRUCTS?1, 2, 3 CHRISTIAN HEISS MATTHIAS ZIEGLER Te!nis!e Universität Mün!en Humboldt Universität zu Berlin KAI ENGBERT!AND!PETER GRÖPEL RALF BRAND Te!nis!e Universität Mün!en Universität Potsdam Summary.—Self-leadership and volition are conceptually similar concepts. Both propose self-inuence strategies that aim to improve the motivation and self-direction necessary to perform well. The present study assesses whether self-leadership strategies maintain construct-specic variance when compared with the similar strategies of volition. Results from a questionnaire study (N"="320) indicate that self-leadership and volitional strategies are distinguishable and only moderately (r"=".33) correlated. Self-leadership, therefore, supplements volition during goal attainment. Findings are discussed in light of the Rubicon model of action phases. Self-leadership is a relatively new construct rooted in organizational psychology (Manz, 1986). This construct is intuitively appealing for practitioners because it provides individuals with ready-to-use strategies to guide behavior (e.g., self-reward, visualizing successful performance). However, the construct validity of measures of self-leadership remains questionable because the relationships of these measures to questionnaires that tap other constructs have barely been investigated (Neck & Houghton, 2006). The present research focuses on the construct validity of self-leadership. We investigate whether a well-tried self-leadership measure displays incremental validity when compared with a questionnaire that assesses the similar concept of volition. Self-leadership Self-leadership is dened as an inner-leading process to achieve selfdirection and self-motivation necessary to perform (Neck & Houghton, 2006). This self-leading process is further specied as an intentional use of self-leading strategies, which can be divided into three general categories labeled as behavior-focused strategies, constructive thought pa#ern strategies, and natural reward strategies (Houghton & Neck, 2002).

HEISS, ET AL. havior-focused strategies are adapted from the concept of self-management that aims to meet external goals and to facilitate the accomplishment of necessary but possibly unpleasant tasks. These strategies include self-observation, self-goal se#ing, self-reward, self-punishment, and selfcueing. Constructive thought pa#ern strategies constitute the rst facet through which self-leadership expands self-management, which was limited to the aforementioned behavioral strategies. Cognitive strategies are designed to build and maintain functional thinking pa#erns, including evaluation of beliefs and assumptions, positive self-talk, and visualization of successful performance. Natural reward strategies constitute the second facet through which self-leadership expands self-management. They emphasize the enjoyable aspects of a given task, including e%orts to incorporate more pleasant and enjoyable features into a task, changing realizations of the task by focusing on the task’s rewarding aspects, or purposefully choosing a task that a person enjoys doing (Houghton & Neck, 2002). In summary, self-leadership represents a broader concept of self-inuence by addressing external and internal standards in relation to performed actions (e.g., evaluating personal meaningfulness of a given task). Thus, e%ective self-leaders know why they want to perform a task, rather than feeling obligated to perform it (e.g., through recognizing rewards that result from performing activities themselves). Volition The concept of volition was introduced to bridge the gap between choice and action. Volition maintains intentions, especially when they compete with strong alternative action tendencies and whenever a goal su%ers from insu&cient motivational support (Kuhl & Goschke, 1994). Following the theory of volitional functioning (Kuhl, 2000), volition was decomposed into a set of conscious and unconscious strategies that aimed to support goal-striving processes. These strategies include motivation control (i.e., enhancing the subjective a#ractiveness of an intended action; Kuhl, 2000), emotion control (i.e., disengaging from a sad mood if it renders the enactment of an intention di&cult; Gross, 1999), a#ention control (i.e., focusing a#ention on aspects that are relevant for implementing the current intention; Muraven & Baumeister, 2000), self-determination (i.e., choosing and performing self-concordant goals; Kuhl & Fuhrmann, 1998), decision control (i.e., using mechanisms to arrive at a decision quickly and avoid rumination; Kuhl, 1994), and coping with failures (i.e., disengaging easily from intrusive thoughts and failure, rather than persevering with an aversive experience; Kuhl, 1994). Prior Research on Construct Validity Research that focuses on the construct validity of questionnaires that 13Heis447-462.indd 448 9/3/2010 10:43:17 AM SELF-LEADERSHIP AND VOLITION 449 measure self-leadership or volition is limited to investigating relationships with associated personality traits. Inspecting the construct of self-leadership, Houghton, Bonham, Neck, and Singh (2004) reported three ndings in their study. A positive, significant relationship was observed between self-leadership and personality traits of extraversion and conscientiousness. Self-leadership was distinct from personality traits on the lowest level of abstraction, representing selfleadership strategies. Self-leadership and personality were statistically indistinguishable at the construct level. However, the la#er nding must be regarded with great caution. The authors constructed a general personality factor consisting of extraversion, emotional stability, and conscientiousness. Even though such general factors have been proposed (Rushton & Irwing, 2009), they are highly controversial (Ashton, Lee, Goldberg, & de Vries, 2009) and might simply reect variance due to socially desirable responding (Ziegler & Bühner, 2009). In addition, the latent correlation observed between this factor and the general self-leadership factor is corrected for a#enuation. These corrections boost latent correlations strongly if loadings are weak, as was the case in that study (Bühner, Krumm, & Pick, 2005). The authors did not directly test whether a true correlation existed. Thus, there is ample reason to doubt the conclusions drawn. For this reason, this relationship is re-examined in the present study. Inspecting the construct of volition, Kuhl (2000) showed that relationships with personality were consistent with theoretical assumptions of volitional functioning. The ndings illustrate negative correlations with neuroticism, in particular for skills of decision and failure control, and positive correlations with extraversion for skills of self-determination and motivation control (Forstmeier & Rüddel, 2008). Moreover, Kuhl and Kazén (2003) pointed out that personality traits such as neuroticism determine individual sensitivity to negative a%ect, whereas volitional competence determines individual regulation of negative a%ect to initiate and enact intended actions. Research Comparing Self-leadership With Volition Thus far, self-leadership and volition have been analyzed separately; no empirical research compares self-leadership and volition in one coherent study to assess construct overlap. Such concept comparisons are limited to theoretical considerations, leading to ambiguous results. On the one hand, it seems reasonable to suspect that self-leadership and volition are indistinguishable on a conceptual level. Both concepts have similar functions during the goal-a#ainment process (e.g., to ensure goal a#ainment). In particular, this similarity refers to behavioral strategies of self-leadership (e.g., self-cueing), which aim to accomplish necessary but possibly 13Heis447-462.indd 449 9/3/2010 10:43:17 AM 450 C. HEISS, ET AL. unpleasant tasks. Similarly, the volitional strategy of a#ention control can be used to shield a goal intention when the goal set appears less a#ractive. In addition, conceptual similarities can be identied in intended outcomes because both concepts aim to improve the motivation and self-direction necessary to perform well. On the other hand, it seems equally reasonable to suspect that the concepts can be distinguished. At least in part, self-leadership has a di%erent scope compared with volition because proposed strategies can be used to assist motivational goal-se#ing and goal-evaluation processes. For example, using a strategy such as positive self-talk facilitates individual condence about set goals and helps to end deliberation processes about goal engagement. In addition, strategies such as self-reward or the evaluation of beliefs and assumptions assist individuals in evaluating the appropriateness of performed actions. These motivational processes are not within the scope of volition. In particular, volitional strategies are designed to cope with failure and setbacks, which, in turn, is not within the scope of self-leadership. Thus, it can be argued that self-leadership may provide a complementary set of strategies, compared with volition, which can be used to assist in goal se#ing and goal evaluation. Goal of Present Study The concept of self-leadership may be redundant in relation to the concept of volition (Markham & Markham, 1995), although researchers argue that the distinct nature of self-leadership is primarily based on its unique set of self-leading strategies (Neck & Houghton, 2006). Until now, this suggestion has lacked empirical support because no empirical research has been done to assess whether these self-leadership strategies maintain construct-specic variance when compared with similar strategy-based concepts, e.g., volition (Kuhl & Fuhrmann, 1998). For this reason, in the present study, self-leadership and volition were examined from a construct validation perspective. This perspective avoids unwarranted substantive conclusions and inadequate applications of the constructs (Diefendor%, Hall, Lord, & Stream, 2000). The magnitude of empirical overlap between self-leadership and volition was investigated using exploratory factor analysis (EFA). These results were conrmed in conrmatory factor analyses (CFAs). Discriminant validity was assessed by inspecting correlations of self-leadership and volition related to associated Big Five personality traits (McCrae & Costa, 1999) by using latent regression analysis. M Participants Undergraduate students (N"="320; 186 women, 134 men) took part in 13Heis447-462.indd 450 9/3/2010 10:43:17 AM 451 SELF-LEADERSHIP AND VOLITION the study. Their mean age was 24.2 yr. (SD"="4.5). All subjects participated voluntarily and signed a le#er of consent to participate. They were told that the data obtained would be used exclusively for research purposes and recorded in such a manner that participants could not be identied, directly or through identiers linked to the subject. Therefore, approval by an institutional ethics board was not necessary. At the end of the study, participants were given 10 Euros for their participation. Measures Self-leadership, volition, and personality were measured with validated questionnaires. Psychometric properties of all scales used are listed in Table 1.

The questionnaire consists of 27 items in nine subscales. The subscales are as follows: self-goal se#ing (example item: “I establish specic goals for my own performance”), self-reward (“When I have successfully completed a task, I o$en reward myself with something I like”), selfpunishment (“I tend to be tough on myself in my thinking when I have not done well on a task”), self-observation (“I pay a#ention to how well 13Heis447-462.indd 451 9/3/2010 10:43:17 AM 452 C. HEISS, ET AL. I’m doing my work”), self-cueing (“I use wri#en notes to remind myself of what I need to accomplish”), focusing thoughts on natural rewards [“I seek out activities in my work (school) that I enjoy doing”], visualizing successful performance (“I visualize myself successfully performing a task before I do it”), self-talk [“Sometimes I talk to myself (out loud or in my head) to work through di&cult situations”], and evaluating beliefs and assumptions (“I think about and evaluate the beliefs and assumptions I hold”). Participants responded by using a 5-point Likert-type scale with anchors 1: Not at all accurate and 5: Completely accurate. Adequate reliability and construct validity of the RSLQ–D have already been demonstrated (Andressen & Konradt, 2007). Volitional strategies.—The volitional strategies under investigation were motivation control, emotion control, a#ention control, self-determination, decision control, and coping with failure. The respective scales were taken from two questionnaires: the Volitional Components Inventory (VCI; Kuhl & Fuhrmann, 1998) and the Action Control Scale (ACS– 90; Kuhl, 1994). Consisting of four items each, the subscales of the VCI are as follows: motivation control (example item: “I am capable of nding the pleasant aspects of an initially unpleasant activity”), emotion control (“I can reduce my tension level if it becomes disturbing”), a#ention control (“When I want to concentrate on something my thoughts o$en wander”), and self-determination (“I feel that most of the time I really want to do the things I do”). Participants responded to all items on a 4-point Likert-type scale with anchors 1: I completely disagree and 4: I completely agree. In the present study, internal consistency reliability of all scales was greater than !">".70. This resembles prior ndings (Kuhl & Fuhrmann, 1998; Fröhlich & Kuhl, 2004). The ACS–90 subscales measuring decision control and coping with failure consisted of 12 items each. Items describe stressful situations accompanied by two alternative ways of coping with each situation. Participants are asked to select the response that best resembles their personal way of coping with the situation. An example item of the decision-related dimension is, “When there are two things that I really want to do, but I can’t do both of them: (a) I quickly begin one thing and forget about the other thing I couldn’t do (high decision control), or (b) It’s not easy for me to put the thing that I couldn’t do out of my mind” (low decision control). An example item of the failure-related dimension is, “When I am told that my work has been completely unsatisfactory: (a) I don’t let it bother me for too long (high coping with failure), or (b) I feel paralyzed” (low coping with failure). In the present study, both decision- and failure-related dimensions showed adequate internal consistency reliability of .77 and .73, respectively, similar to prior ndings (Diefendor%, et al., 2000). 13Heis447-462.indd 452 9/3/2010 10:43:17 AM SELF-LEADERSHIP AND VOLITION 453 Personality.—Personality traits were measured with an abridged version of the Big Five Inventory (BFI–K; Rammstedt & Oliver, 2005). The BFI–K consists of 21 items that measure personality with ve subscales, following the Five-Factor Model of Personality (McCrae & Costa, 1999). Therein, extraversion (example item: “I see myself as someone who is talkative”), neuroticism (“I see myself as someone who is depressed, blue”), conscientiousness (“I see myself as someone who does a thorough job”), and agreeableness (“I see myself as someone who is helpful and unselsh with others”) are measured with four items, whereas openness to experience (“I see myself as someone who is original, comes up with new ideas”) is measured with ve items. Participants responded by using a 5-point Likert-type scale with anchors 1: Not at all true and 5: Completely true. Su&cient reliability and construct validity of the BFI–K have been demonstrated (Rammstedt & Oliver, 2005). Statistical Analyses Data were analyzed in three steps. First, an exploratory factor analysis (EFA) with maximum likelihood method and promax rotation was used to explore whether the two concepts could be di%erentiated. EFA was performed with half of the total sample to cross-validate results later. As the interest was the extent to which self-leadership and volitional subscales overlap, subscale scores were used for the analysis. To select the number of factors to be extracted, the minimum average partial test (O’Connor, 2000) was applied. The model suggested by the EFA was specied and tested with AMOS 17, which calculated a CFA with the other half of the sample. Two alternative models implied by theoretical considerations regarding relationships between self-leadership and volition were also tested to see if the model identied in the EFA had the best t. Latent regression analysis was performed to assess whether individual self-leadership and volitional competence are distinct from associated personality traits of the Big Five. R Descriptive statistics are listed for all study variables in Table 1. Exploratory Factor Analysis Statistical prerequisites for conducting an EFA were satisfactorily fullled (Bartle#’s test of sphericity, "²"="737.00, df"="105, p"<".01; Kaiser-MeyerOlkin measure of sampling adequacy"=".81). The minimum average partial test suggested a two-factor solution, which explained 43.9% of the total variance. Table 2 shows that Factor 1 mainly encompassed the respective self-leadership subscales, whereas Factor 2 comprised all volitional subscales. 13Heis447-462.indd 453 9/3/2010 10:43:17 AM 454 C.

Communalities of subscales, ranging from .07 (self-reward) to .64 (self-motivation), pointed to the possibility that several subscales (e.g., focusing on natural rewards; a#ention control) are not represented well by the two-factor solution. Consequently, an alternative three-factor solution was tested, consistent with the eigenvalue-greater-than-one test. Factor loadings indicated increased overlapping variance between factors, resulting in an ambiguous pa#ern matrix. The added factor could not be interpreted as unique because of multiple double loadings. Therefore, it was concluded that the two-factor solution is more appropriate to examine the extent to which self-leadership and volitional strategies overlap because the pa#ern matrix reveals more consistent and clearer interpretable factors. Consistent with the theoretical assumption that there should be empirical overlap between self-leadership and volitional strategies, the pattern matrix shows substantial double loadings between the two factors. Using Kline’s recommended (1997) critical value of .20 as a cuto%, selfpunishment, focusing on natural rewards, and coping with failure were identied as showing substantial double loadings, indicating overlapping variance between factors. The correlation between the two factors extracted was moderate (r"=".33), which means that the two factors indeed overlap on a few subscales but also have su&cient specic variance. Thus, analysis suggests self-leadership and volition can be modeled with two correlated factors. 13Heis447-462.indd 454 9/3/2010 10:43:17 AM SELF-LEADERSHIP AND VOLITION 455 Conrmatory Factor Analyses The purpose of the CFA was to cross-validate the EFA model more rigorously and to compare it with a one-factor model and a two-factor model. Model 1 specied self-leadership and volition as loading on a single latent variable (g-factor), proposing that self-leadership and volition are indistinguishable constructs. Model 2 posited that self-leadership and volition are distinct (i.e., uncorrelated) constructs, with all self-leadership subscales loading on a latent variable labeled self-leadership and all volitional subscales loading on a latent variable labeled volition. Within the measurement model, double loadings were specied from EFA results (self-punishment, focusing on natural rewards, and coping with failure). Model 3 mirrored Model 2 but included a correlation between the two latent variables. This model is fully in line with the EFA results reported earlier. Goodness of t of the models was evaluated by using the chi-squared statistic and the comparative t index (CFI), the standardized root mean square residual (SRMR), and the root mean square error of approximation (RMSEA). Because chi square is a%ected by violations of multivariate normality in these data (multivariate kurtosis"="12.55, critical ratio"="4.97), a Bollen-Stine bootstrap correction (1,000 bootstrap samples) was performed. Multiple t indices were used because they provide a more conservative and reliable evaluation of the solution. Following recommendations of Beauducel and Wi#mann (2005), an acceptable model t was dened by the following criteria: CFI">".95, SRMR"<".80, and RMSEA"<"0.06. Note that the CFI tends to incorrectly reject trait models with low loadings, making less strict cuto%s necessary (Beauducel & Wi#mann, 2005). To ascertain the best #ing model, Akaike’s information criterion (AIC) was estimated additionally. Table 3 summarizes the t indices for all three models. One double loading found in the EFA was not signicant (motivation control on self-leadership), whereas all other loadings were signicant. As can be seen in Table 3, all "2 values were signicant (p"<".001), indicating poor model t. However, the mist was not large. Model 3, replicating EFA results, performed best. The latent correlation was .37. This nding validates results obtained by EFA and indicates that self-leadership and volition share empirical overlap on a scale level, but should be regarded as conceptually distinguishable constructs. To achieve the best power for the next analysis, a multiple group invariance test (Byrne, 2004) was used to test whether both subsamples could be combined. With this approach, four types of invariance were tested: congural (the same measurement and structural model is used in both samples), measurement weights (cor- 13Heis447-462.indd 455 9/3/2010 10:43:17 AM 456 C.

Because all models were nested, they could be compared using "2 di%erence tests. Results showed that no model signicantly di%ered from another model by simply assuming congural invariance (see Table 3). Thus, the samples were merged again. Latent Regression Analyses Within the latent regression model, volition and self-leadership were regressed on the Big Five. Results showed that Neuroticism (#"="'.59, p"<".001), Openness (#"=".19, p"<".001), and Conscientiousness (#"=".50, p"<".001) explained a large part of volition (R2"=".64). For self-leadership, the same predictors had signicant regression weights, Neuroticism (#"=".16, p"<".01), Openness (#"=".21, p"<".001), and Conscientiousness (#"=".44, p"<".001), which explained a considerably smaller part of self-leadership variance (R2"=".31). The latent correlation controlling for the Big Five was .61. Clearly, a suppression e%ect occurred. Thus, self-leadership is primarily related to Conscientiousness, whereas volition is primarily related to emotional stability (reverse pole of Neuroticism). These results indicate that self-leadership and volition have di%erent correlations with the Big Five personality traits. Moreover, neither one could fully be explained by the Big Five. D The aim of the present study was to examine whether self-leadership and volition are distinguishable constructs. Results of EFA revealed that subscales can be identied as two correlated factors interpretable as selfleadership and volition. Results of the conrmatory factor analysis also indicate that a two-factor model ts best. Latent regression analyses re- 13Heis447-462.indd 456 9/3/2010 10:43:18 AM SELF-LEADERSHIP AND VOLITION 457 veal di%erential correlation pa#erns with the Big Five personality traits. In this regard, Conscientiousness accounted most for self-leadership, whereas Emotional Stability accounted most for volition. In summary, there is empirical evidence that self-leadership and volition are distinguishable, albeit moderately correlated concepts. The magnitude of empirical overlap between self-leadership and volitional strategies as measured is smaller than expected. This result may be explained by the fact that self-leadership and volitional strategies serve di%erent functions within goal a#ainment. Whereas self-leadership strategies assist the motivational processes of goal se#ing and goal evaluation, volitional strategies support the goal-striving process. This observation is in line with the theory of volitional functioning (Kuhl, 2000). Here, it is assumed that all volitional strategies share two similar functions: they are benecial for overcoming barriers or di&culties and for ensuring goal striving. Results point to the possibility that the two concepts should be portrayed as supplemental. For example, self-leadership strategies are primarily benecial for creating goal intention, whereas volitional strategies ensure that this goal intention is transformed into behavior, particularly when di&culties appear. Thus, the assumption that self-leadership comprises a unique construct (Neck & Houghton, 2006) should be so$ened: self-leadership is supplemental to volition. Supplemental aspects of self-leadership compared with volition become evident when both concepts are regarded from a meta-perspective on action phases, e.g., in light of the Rubicon model (Beckmann & Gollwitzer, 1987; Heckhausen & Gollwitzer, 1987). F. 1.(Interaction of self-leadership and volitional strategies within the goal a#ainment process using the Rubicon model of action phases. 13Heis447-462.indd 457 9/3/2010 10:43:18 AM 458 C. HEISS, ET AL. The Rubicon model of action phases structures the route from wishes to actions into four phases. The predecisional phase is characterized by deliberation between di%erent goals. A$er deciding on a concrete goal (and therefore having crossed the Rubicon), the individual then moves to the preactional phase, in which concrete actions are planned. Therea$er, actions implied by the chosen goal are executed (actional phase). In the postactional phase, the person nally evaluates the successfulness of goal a#ainment. The predecisional and the postactional phases are regarded as motivational, whereas the preactional and the actional phases are volitional (Gollwitzer, 1991). Volitional strategies may be used predominantly when goal pursuit becomes demanding, which is likely in the preactional and the actional phases (Gollwitzer, 1991). For example, the volitional strategy decision control supports the end of planning activities and the commitment to begin acting when possible action alternatives are numerous and the risk of ruminating is high. A#ention control and coping with failures are needed during the actional phase to focus on a task and to cope with unexpected defeats and di&culties. In contrast, self-leadership strategies may be used predominantly when goals are set and evaluated, which takes place in the predecisional and the postactional phases. For example, focusing on natural rewards or visualization of successful performance both facilitate the decision-making process and enhance the motivation to set a goal. Similarly, self-leadership strategies such as selfreward or the evaluation of beliefs and assumptions both facilitate evaluation of goal a#ainment. The assumption that self-leadership and volitional strategies can be used in di%erent action phases should not tempt one, however, to constrain the use of self-leadership or volitional strategies to these specic phases exclusively. Either self-leadership (e.g., focusing on natural rewards) or volitional strategies (e.g., motivation control) can be used to compensate for insu&cient motivation and to facilitate accomplishment of necessary but unpleasant tasks, as shown by the moderate correlation (.33) between constructs. However, low communalities of subscales (e.g., self-reward or a#ention control) indicate that several subscales are represented inadequately through the corresponding latent factor. A possible explanation for selfleadership subscales might be that they are not deduced from a consistent theoretical framework. A possible explanation for volitional subscales might be that existing measures mix volitional abilities and volitional strategies. Volitional abilities indicate whether a person is able to use volition when necessary. For example, a#ention control is captured as reversed with items such as, “When I want to concentrate on something, my thoughts o$en wander.” 13Heis447-462.indd 458 9/3/2010 10:43:18 AM SELF-LEADERSHIP AND VOLITION 459 The subscale assesses whether an individual is able to control a#ention or not. Volitional strategies indicate what a person does to apply volition. For example, motivational control is captured with items such as, “When I am performing a di&cult task, I intentionally focus on positive aspects.” The subscale assesses a strategy because ready-to-use advice on how to enhance the a#ractiveness of performed actions can be inferred. Future Research and Limitations To date, the uniqueness of the self-leadership concept has been based on conceptual considerations, emphasizing that this concept provides individuals with a unique set of self-leading strategies (Neck & Houghton, 2006). This assumption was tested empirically for the rst time, demonstrating that proposed self-leadership strategies are only partially distinct from volition. Although results point to the possibility that the self-leadership construct is worthy of its own standing, this possibility can be regarded as a prerequisite for studying self-leadership more systematically. For that purpose, results specify that motivational-enhancing aspects of self-leadership (e.g., positive self-talk) are essential supplements to volition. In contrast, existing overlap indicates that encompassed strategies to assist goal-striving processes are redundant because they are already captured by volition. The relatively large amount of explained variance also raises the question of whether volition might not be be#er understood as a combination of di%erent Big Five facets, mainly Neuroticism and Conscientiousness. Future research should therefore use broader Big Five questionnaires that allow the di%erentiation of facets and compare them with volition. The same, of course, holds true for self-leadership. Thus, the results presented here specify directions for rening the theory of volition and self-leadership in future research. Integrating self-leadership into the Rubicon model of action phases allows be#er di%erentiation of the interactions between self-leadership and volition within the goal a#ainment process. This integration claries self-leadership’s function during goal a#ainment, is a rst step in dening the concept’s standing within motivational psychology, and provides a valuable framework to spur future research. Some limitations of the study need to be addressed. First, the notion that self-leadership and volitional strategies serve di%erent functions within the goal-a#ainment process resulted from an interpretation of data. This assumption does not represent an empirical nding, and researchers are encouraged to test it. For instance, experimental studies could systematically test at di%erent action phases of the Rubicon model to assess whether the use of self-leadership or volitional strategies can 13Heis447-462.indd 459 9/3/2010 10:43:18 AM 460 C. HEISS, ET AL. be mapped to specic action phases. Second, the data suggest conceptual and measurement problems regarding self-leadership and volition. This could limit conclusions drawn from this research. Prospective research should elaborate correlations of self-leadership and volition with convergent and discriminant constructs (e.g., personal initiative; Frese, Fay, Hilburger, Leng, & Tag, 1997) as well as criteria. For example, experimental studies could assess whether associated dependent variables (e.g., number of goals set or number of goals reached) can be predicted uniquely from these concepts. Showing that self-leadership is conceptually distinguishable from volition is prerequisite to its potential for further elaboration beyond organizational psychology, particularly in applied domains such as clinical or sports psychology, because it provides individuals with ready-to-use strategies to guide behavior. However, self-leadership must be complemented not just on theoretical grounds, but also on empirical grounds, before being transferred to other domains. Hence, this research can be regarded as a rst step, as a contribution to understanding of self-leadership on a conceptual level, and as a starting point for e%orts to extend its usefulness beyond organizational psychology.
